The Bagdad Battery

Sitting in the National Museum of Iraq is a earthenware jar about the size of a man's fist. Its existence could require history books throughout the world to be rewritten.The little jar in Baghdad suggests that Volta didn't invent the battery, but reinvented it. The jar was first described by German archaeologist Wilhelm Konig in 1938. It is unclear if Konig dug the object up himself or located it within the holdings of the museum, but it is known that it was found, with several others, at a place called Khujut Rabu, just outside Baghdad.

Probably got looted during the recent war
